Must everything the hand touched be washed after it touched a garment wet with urine, knowing that among the things touched was a phone that would be damaged by washing?

Impurity is purified by pouring water over it. If a wet hand touches it, the hand becomes impure and is purified by pouring water over it. As for items that would be damaged by washing, such as mobile phones, wiping them suffices. Impurity is not transferred if the hand is dry when touching the impure object.
